TYPE on MATRIX.

Specification of Letters Patent.

Patented Aug. ML, 191?.

To all whom it may concern:

Be it known that I, GEORGE B. MGOARTY, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a new and useful Improvement in Type or Matrices, of which the following is a specification.

My invention has reference to typographical machines, such, for instance, as linotype machines of the kind illustrated in Letters Patent of the United States No. 436532, to O. Mergenthaler, wherein printingbars or slugs having type characters on one edge are cast in a slotted mold against a composed line of matrices presented momentarily thereto. In these machines the composed line is ordinarilv made up of a series of individual matrices which are released by a keyboard from a magazine in the Order in which their characters are to appear in print and then assembled side by side in line. In special kinds of work, however, the composed line consists of a single matrix, commonly known as a quad-block, which carries a long strip containing the formative cavity against which the slug is produced. Such quad-blocks are generally employed in the production of printing rules, borders, dashes and the like.

It is the aim of my present invention specifically to provide a quad-block of the kind mentioned whereby the position of the print- I ing surface on the slug may bevaried edge wise thereof, that is, nearer its upper or lower side, as the case may be. This capability is advantageous for a variety of reaever, that the invention is equally applicable to matrices of ordinar construction such as those first referred to and which are provided with letter characters, etc., it being noted that thecapability'of varying the position of the individual type characters edgewiseof the slug may be made use of in many instances.

To accomplish the above result I mount the character-bearing strip in the quad-block so that it may be adjusted to different vertical positions therein,and thus permit the character to be set in any required position across the mold slot to correspond to the de quad-block as commonly employed in linotype machines, but obviously many variations and modifications thereof and in its mode of appllcation will be possible and still be comprised within its spirit. Thus, for instance, it may be applied to other kinds of typographical machines and also to type or dies, which are formed with male characters instead of intaglio ones as in the form illustrated. Generally speaking I desire it to be understood that I do not limit myself to any particular form or embodiment except in so far as such limitations are specified in the claims.

Referring to the drawing:

Figure 1 is a face view of a quad-block constructed in accordance with my invention;

Fig. 2 is a transverse vertical section thereof;

Fig. 3 is a perspective view of the block shown in Fig. 1; and

Fig. 4:.21Ild 5 are detail-views.

The quad-block is of the ordinary construction, consisting of a body portion 1, provided on its front and rear sides with projecting lugs for supporting it in position in the machine, and also a strip or portion 7 located in the front side of the body portion and containing the formative cavity 8, which in the present instance is designed for the production of a straight rule or border. It will be understood, of course, that the cavity may be of anv desired description, depending upon the character of printing surface required.

As before stated, the present invention contemplates the support ofthe character bearing strip 7 in the body portion 1 so that it may be set in difierent vertical positions therein. To this end the strip 7 is mounted at its opposite ends in a pair of blocks 2 and '3 which are slidably arranged in vertical iiotchesQ and 3* formed in the body portion 1 of the quad-block, it being noted that the blocks 2 and 3 are formed with inwardly projecting flanges 2 and 3 which engage in vertical slots 2 and 3 in the body portion and thus prevent the forward or lateral displacement of the blocks. It will also be noted that the character-bearing strip 7 is connected to the two blocks by means of a dove-tail, which not only permits the strip to be removed and replaced, but in addition serves to maintain it in proper position when inserted.

In order to permit the vertical adjustment of the strip 7 the body portion 1 is provided with a recess 1, which is of such width as to allow the strip to be adjusted up or down to any required extent. This adjustment of the strip is effected by means of a pair of set screws 4 which pass through the under side of the body portion and engage the bottom edge 'of the strip near its opposite ends, a spring 5, whose opposite ends are seated in recesses 6 in the upper side of the body portion, bearing upon the upper edge of the strip 7 and tending constantly to maintain it yieldingly in engagement with the set screws. As a result, by turning the screws 4 in one direction or the other, the character bearing strip may be raised or lowered to set the formative character 8 in any desired position. It will also be observed that by turning the screws 4 to unequal extents, the formative character may be set in different angular positions, that is, it may be caused to extend diagonally across the quad-block, so as thus to produce on the slug a diagonal printing surface.

As previously stated, I have shown my invention in preferred form and by way of example, but obviously many variations and alterations therein will suggest themselves to those skilled in the art without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:

1. A type or matrix for a slug casting machine, comprising a body portion adapted to be supported in fixed relation to the mold employed in said machine, a character bearing portion slidably mounted in the body portion so as to be adjustable vertically relatively thereto to vary its position with respect to the mold, and means for holding the character bearing portion in its adjusted position.

2. A type or matrix for a slug casting machine comprising a body portion adapted to be supported in fixed relation to the mold employed in said machine, and formed with a recess in the side facing the mold, and a character bearing portion seated-in said recess and slidable vertically therein to vary the position of its character with respect to the mold.

3. A type or matrix for a slug casting machine comprising a body portion adapted to be supported in fixed relation to the mold employed in said machine, a character bearing portion slidably mounted in the body portion so as to be adjustable vertically relatively thereto to vary the position of its character with respect to the mold, and means for efi'ecting such vertical adjustment of the character bearing portion.

4. A type or matrix for a slug casting machine comprising a body portion adapted to be supported in fixed relation to the mold employed in said machine, a character bearing portion slidably mounted in the body portion so as to be adjustable vertically in opposite directions to vary the position of its character with respect to the mold, adjusting means to move the character bearing portion in one direction, and a spring tending constantly to 'move it in the opposite direction.

5. A quad block for a slug casting machine consisting of a body portion adapted to be supported in fixed relation to the mold employed in said machine, and a character bearing strip slidably mounted in the body portion so as to be adjustable to difierent vertical positions therein to vary the location of its character with, respect to the mold.

6. A quad-block consisting of a body portion formed with a recess and a characterbearing strip adjustably mounted in thev recess, said body portion being provided with a pair of adjusting screws arranged in engagement with one edge of the character-bearing strip near its opposite ends.

7. A quad-block consisting of a body portion formed with a recess and a characterbearing strip adjustably mounted in the recess, said body portion being provided with a pair of adjusting screws arranged in engagement with one edge of the characterbearing strip near its opposite ends, and also with a spring arranged in engagement with the opposite edge of the character-bearing strip.

8. A quad-block consisting of a body portion providedat its opposite ends with a pair ofsupporting blocks slidable vertically therein, and acharacter-bearing strip seated in the supporting blocks so as to be movable therewith.

9. A quad-block consisting of a body portion provided at its opposite ends with a pair of supporting blocks slidable vertically therein, and a character-bearing strip seated in the supporting block so as to be movable therewith, said character-bearing strip being detachably connected to the supporting blocks so as to be removable at will.

10. A quad-block consisting of a body portion provided at its opposite ends with supporting blocks slidable vertically therein, and a character-bearing strip seated in the supporting blocks, the said body portion being provided at its under side with a pair of adjusting screws bearing againstthe lower edge of the character-bearing strip and at its upper side with a spring bearing on the upper edge of the strip.

11. A type or matrix for a slug casting machine comprising a body portion adapted to be supported in fixed relation to the mold employed in said machine and formed 10 with a recess in the side facing the mold,

and a strip or member seated in said recess and provided with a single matrix character, the said member being adjustable vertically Within the recess to locate the matrix character in different operative positions 15 With respect to the mold.
